hi,

i was wondering if anyone has succeeded in getting dd-wrt onto a netgear wgt634u ?

i am contemplating putting the atheros version of one of the BS builds of the pre rc7 versions. would this be the right version to try?

regards

here is what i have so far.

i have flashed the device with openWGT, a version openwrt developed for the wgt634u. it works but is very basic. attached is the cfe.bin and the nvram.bin

the nvram is very simple, most of the settings have to be entered after flashing.

below is a portion of the text the openwrt wiki has on this unit.

"The WGT634U is based on the Broadcom 5365P board that features a 200 MHz MIPS CPU along with a built-in IPSEC co-processor details, allowing encrypted VPNs (up to AES256) a bonus of a performance boost up to 75Mbps (quoted) IPSec throughput - far more than the MIPS32 CPU alone can produce.

It also comes standard with 8 MB flash and 32 MB RAM. The 8MB flash is an Intel te28f640 tsop pin chip with 56 pins. The 32MB of RAM are ICSI IC42S26800 chips with 54 tsop pins on a 16-bit bus. As many SDR & DDR PC memory chips also use 54 pin tsop memory, it is possible to remove two identical larger chips that are also on a 16-bit bus from a memory stick and replace the stock RAM on the WGT634u. Great care would need to be taken to ensure that the replacement chips matched the pinout in the datasheet link provided. In theory, the Intel flash could also be de-soldered and replaced. However, no known case of either has been reported.

The wireless NIC is an Atheros Mini-PCI capable of 802.11b/g, and has a MS-156 test point and a soldered antenna. The WGT634U also has a USB 2.0 controller."

Also attached is a picture from the same wiki page of the device.

the openwgt i have flashed has working usb and no boot wait. the unit has serial but i have not connected to it. not sure about jtag.

Looks like interesting device. I'll check detection, then it might work with broadcom_atheros builds.

For start it will be nice to get JTAG and console working.

from what i have read jtag seems to be crippled on the board. serial is fine and many folks have used this method to gain access to the device.

i have never used serial but i have enough parts to make up a serial connection.

i'm happy to try anything out,

here are a few links to sites relating to the wgt634u

As far as JTAG, don't believe everything you hear, we just need to do some testing of our own !

Yes, because support for it's cpu was wrong. But in tjtag it's fixed.
